There are two main topologies of single-phase inverters; half-bridge and full-bridge topologies. This application note focusses on the full-bridge topology, since it provides double the output voltage compared to the half-bridge topology.
In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated. It is also discussed that the DC-link capacitor of the inverter is a limiting factor.
Classification of single-phase transformerless inverter topologies used in PV systems according to DC-link voltage. llustrates the junction temperature curves of the semiconductors in turn-ON and turn-OFF conditions. The maximum junction temperature is related to the bipolar F-B inverter , and hence the maximum losses occur through the
In this review work, some transformer-less topologies based on half-bridge, full-bridge configuration and multilevel concept, and some soft-switching inverter topologies are remarked as desirable for grid-connected single-phase PV inverters with respect to high efficiency, low cost, and compact structure.
Neutral-point-clamped (NPC) inverters are the most widely used multilevel inverter topology in high power applications. Figure-1 shows some variants of this topology. Figure-1ab shows the topology of a three-level and five-level inverter respectively.
The semiconductors of each branch are complementary in performance, which is to say when one is conducting the other is cut-off and vice versa. This topology is the most widely used for inverters. The diagram in Fig. 1 shows the circuit of a full-bridge topology for a single-phase inverter.
